EPC light came on last night on my s3 8p mtm330 7wks out of warranty so it went into audi this morning they are now telling me my ecu is buggered it is going back in tommorrow for a better look but more than likely they are going to reflash it back to 265bhp as they are not a mtm dealer, am i due any compensation for my £1000 mtm map as it seems to be a common fault in the bosch ecu? Any vw/audi specialists in the house that can shed some light on my situation? Cheers, Stevie.

Not the dreaded Furry animal in the Ecu!!!!
Our stealthwolf wont sleep tonight!!! :signLOL:
Sorry... forum joke mate.
Im sure one of our S3 owners will come along shortly to help you out fella. :happy2:
-
Yip and the little blighter is hanging on in there not shiftin no matter what i fling at it! I hope so someone can help, nightmare!!!!
-
if they find out your car is mapped, which they will if they interrogate it properly, then not only have you lost the 1k map but they will probably want to charge for a new ecu aswell.
Thats what SEAT would be doing anyway
-
They know about my map the map is an audi map, they replaced turbo, clutch and steering rack all under warranty. The gremlin is not mtm gremlin it is deeper i think it is a bosch fault very common in skoda i hear.
-
never heard of it on briskoda mate
-
I'm sure thats where i read about it. :smiley:
-
other than the light, are there any symptoms? whats the fault codes?
-
No symptoms its running fine. I'm sure the code was p0601?
-
That's a faulty checksum isn't it?
-
Yeah thats what it read? Way above my head.
-
That is the notorious checksum fault that we find in a lot of Bosch Me9 ecu's. a simple software update should solve it, if the car is on non original software then the software needs to be read and the checksum corrected before writing it back to the ECU.
A quick description of a checksum:
We see a man. He has a orange shirt, blue jeans and red shoes (I know, quite Belgian...). That is the data of ECU. Then he has a paper in his pocket, and it says "Belgian, orange shirt, blue jeans and red shoes". That is the checksum.
So we just need to check, whether the checksum and the ECU data match. If they don't, the checksum needs to be corrected accordingly.

@PDT:
I had a strange issue with some of the electronics I'm developing, about two years ago. We incorporate a checksum to validate the data. What we were finding was under excessive noise conditions, the corrupt (random) checksum was once every so often coincidentally correct allowing garbage data to be read. It was an "infinite monkeys + infinite typewriters + infinite time = Shakespeare" type thing. Had to scratch my head to solve that one.
-
What were you developing? what type of 'noise' are you describing?
-
Thanks for the explanation pdt, so i will lose my mtm and back to 265bhp with original software??? Or can the broken bit be re-written in the ecu keeping the mtm?

What the f*ck are you 2 talking about. :stupid: :grin:
-
I think the monkey with the typewriter bought some new blue jeans and red shoes for his trip to shakespear in belgium!
-
I think you should be able to have the dealer carry out the software update from the factory and then ask MTM to reflash your ECU again with the modified updated code.
Alternatively if MTM hold the correct file they could flash it straight to your car and cut Audi out of the loop.
It's just a different software revison.

are you from the UK?
-
Yeah from the uk. Not that fussed about the mtm i've had a good 2.5yrs out of it without a glitch would rather have it than not tho until i organise another map. Stevie
-
audi dealers sound alot better than SEAT ones. SEAT would have pretty much in polite words told you to either cough up or f*ck off.

Need to wait til tomorrow they may still tell me to go away but they have been brilliant up until now, i cant deal with bad unpolite service it would be their lose my first garage were like that massively up their own arse but i cant describe how helpful and polite this team has been.
-
Please keep this post going and up to date, I have the same problem with my GOLF GTI.
I have the same error code (P0601) but on the reader I used it said 'control unit faulty'
As much info as possible please.
Been having a look around and there are loads of occurances of the same thing all over the shop.
What year is the car and mileage as there also seems to be a common trend with that also.
Let us know if you would
Cheers
-
get the dealer to reflash to standard and go to an MTM dealer, eg Kim Collins - QS Tuning. They should reflash for you but will probably charge labour.
-
What were you developing? what type of 'noise' are you describing?
Battery Management System for EV/HEV. We were simulating all sorts of electrical noise - AC, inductive, conductive, all sorts of junk, all at once. Solved it now, such that I think you'd need an EMP to kill the comms!
-
Still no phone call from audi yet. Nj my audi is march 2007 with 32k on the clock??? I said to audi this morning about a common fault and there is an update....they knew nothing about it but would look into it.
-
S3Dubbin
Similar sorts of age and mileage (mines a 56 plate with 29,000 on it)
Makes you think its all planned!!!
Keep me posted
I have got somebody trying to get the latest sofware for me.
Will let you know.
Do you know if its the Bosch ECU on yours?
Cheers
Neil

nj
If you take it to a dealer and it is the ECU update that is required they'll do it for free. If it is also the case that they want to replace your ECU because of a known defect then that should be FoC as well. Things will be made easier if you have a full VW service history as they should have carried out the check during routine servicing.
What would be invaluable is if you could get a copy of the TSB (Technical Service Bulletin)
-
It is def a bosch unit that is in mine nj. Cant believe its so much hassle to try and get an update that all the after market places seem to know abt but bloody audi dont!!! And it certaily aint foc £400 for recon unit or £1400 for a new unit??? They can jog on if they think they are getting a single penny! Still waiting on cust services.
-
The car has been serviced at a local VW / AUDI / BMW garage at the right times using vw parts & all the service is up to date.
The warranty has run out due to the age of the car so where do I stand on a update or ECU replacment FOC?
From what I have read alot of the dealers dont dont even know about this update as it seems to only effect the imported cars which mine and DJGTI's is as well. We have a chap working on a fix at the minute.
Can anybody help me with supplying a link or a copy of the Technical service bullitin for the following fault code.
P0601 - CONTROL UNIT FAULTY
Anybody work at the dealers and had experience of an update fixing this specific problem???
Cheers
-
It can be fixed by somone with the correct equipment if you don't have sucess with VW. Ben at Shark Performance can do it.
-
You can take the car to a reputable ECU tuner and ask them to change just 1 byte of data and correct the checksum and write the file back to the ECU :happy2:
-
Update!!! Latest is one audi garage has no idea abt this update, went to another audi dealership today and they have my car down for an upgrade 2.5yrs ago!!!! No contact from them to say come and get it and why has it taken 2.5yrs for the bug to arrive i have not a clue, anyway my ecu would have been fine if i had this 24h8 update but now my car is mapped and out of warranty i am due no favours, seems a bit harsh??? They say they can sort it for 1hrs labour probably abt £100. What a load of sh*t, the good old car industry shafting its customers as always. Hoping to have my lit up dash fixed by monday.
-
1 hours labour for what is no more than 5 mins work :stupid:
-
As I have said to nj, that should be covered under warranty/goodwill. It is made easier if you have a full Audi Service History because when you take your car for service and they plug it in to VAS one of things they should check is the applicability of any updates. Sadly it's one of the things that is overlooked because the techs won't earn bonus for doing it but they do earn bonus for services etc.
Push them and if necessary push Audi UK. If you are in a rush to have it done then get it done at an approved Audi Centre, keep the invoice and then pursue Audi thereafter.

1 hours labour for what is no more than 5 mins work :stupid:
ECU flash at a dealer is more than 5 mins work, although if they were feeling generous 30 mins would just about cover it but probably wouldn't include a road test etc.
Edited to correct an error
-
Good advice stu cheers never thought abt pursuing it after i have had it done i would have just got it done and that would have been the end of it.
-
The bottom line is you have a car which has a fault, acknowledged by Audi UK and which should have been rectified during a service or visit to an Audi Centre workshop.
They would have been unlikely to contact you directly because it wasn't classed as a recall however lots of Skoda owners were contacted during the recession as dealers were 'looking' for work and subsequent payment from Skoda.

I have some news from this end...........
I have been doing a bit of digging which completes a story.........
When I had the first MOT on it there was a problem with the V5 doc as the Chassis number on the paper work didn't match the car.
What happened was the dealer I bought it off had two golf gti's identical to each other and they incorrectly registered the chassis numbers against the reg plates & nothing flagged up until the 1st MOT.
I have been to the local dealers and asked if mine needs an update and they have printed me a service sheet out which says it has already been done. (the car has never been to the garage it was claimed to be done at)
It was the other car that has had the recall even if it didn't need it and mine has missed out!
I need to sort my paperwork out to prove what happened.
Hopefully I can find it!!
